resetxform does not take effect immediately in C++

[xiesansi]

Hi again,

https://forums.autodesk.com/t5/3ds-max-programming/how-can-i-use-the-resettransform-in-maxscript/td-...

As said in the above thread, the method resetxform works perfectly when triggered in the max listener. But when I call the resetxform maxcript in C++ using ExecuteMAXScriptScript method, the value does not update (mesh data getting by method TriObject->GetRenderMesh) until I make some operation by hand in the modifier plane.

How to force it to take effect immediately?

thank you in advance

I don't understand why use MXS in c++ code?

search ResetXForm in max sdk samples and get how to do it c++ way

[xiesansi]

because we do not want to change the users' file

we change it, get the value, and undo the operation (with undo on in Maxscript)

and all of these are done by Maxscript😅

try to call notifydependence ... call completeredraw ... set modify mode before resetxform ... do resetxform for selected object ... maybe something will help

This all sounds like you go through all that trouble only to get world-space vertex positions for export?

eh ? use c++ to reset xform and do the export then close the file without saving ! no undo required though you can handle the undo using the sdk in various ways.

the easiest way using the sdk is use the code in samples to add the xform modifier

grab the result of the stack with  ObjectState Object::Eval(TimeValue t) do what you need too with the result then

delete the modifier and nothing has changed.
